CHINE CONSTRUCTION FOR STEEL BARRELS Filed Aug. 1, 1945 CHIME CONSTRUCTION FOR STEEL BARRELS Roy C. Ingersoll, Wlnnetka, Ill., assignor to Borg- Warner Corporation, Chicago, 111., a corporation of Illinois Application August 1, 1945, Serial No. 608,189

The present invention relates to metal barrels and more particularly to a novel chime arrangement for steel barrels and the like.

It is one of the principal objects of this invention to simplify the construction of metal barrels such as contemplated herein and to improve the eiliciency, operation and dependability of such barrels.

Another principa1 object hereof is to provide an improved chime structure for steel barrels which will effect a comparatively light construction by eliminating certain components and at the same time will provide a sturdy assembly capable of withstanding severe usage.

Another principal object is to provide a novel arrangement wherein the chimes are assembled with the barrel shell exterior welds, thus reducing the number of parts and eliminating liability of unobserved leakage occurring which heretofore has not been detectable due to obscured or hidden welding.

A further principal object is to provide a barrel with a novel chime ring which is formed from sheet metal and suitably mounted on the barrel sections preferably by welding at the same time other portions such as rolling hoops are welded to the barrel sections.

Still another object is to provide an improved chime ring which is prefabricated or preformed so that it is adapted for telescopic cooperation with a sectional barrel shell that is also preformed in a manner to readily receive the chime ring, the arrangement being such that a plurality of welding operations are effected at the same time on one machine.

A still further object is the provision of a separate chime ring that may be readily attached to the barrel and is so constructed that it provides a continuous and convenient hand grip, and is reinforced in a manner which provides a sturdy support for the barrel body when placed upon its end.

Another object hereof is to provide an improved chime arrangement constituting a convenient hand grip and which protects the tap iltting and the barrel head from damage. In this connection the tap fittin assembly is well back of the plane of the chime where it will not contact the surface on which the chime is resting.

The above-mentioned and other aims and advantages of the present invention will be apparent to persons skilled in the art after the improvements are understood from the within de scription taken in connection with the accom- 5 Claims. (Cl. 220- 74) 2 panying drawings which form a part of this speciflcation, and in which:

Fig. 1 is a fragmentary sectional view partly in elevation showing the improved barrel;

Fig. 2 is a fragmentary plan of a side portion of the chime ring assembly; and

Fig. 3 is a fragmentary elevation of the structure shown in Fig. 2.

The drawings are to be understood as being more or less of a schematic character for the purpose of disclosing a typical or preferred form of the novel chi-me and tap ring arrangement contemplated herein, and in these drawings like reference characters identify the same parts in the different views.

The barrel shown in the drawings is fabricated entirely of metal, preferably sheet steel, of a gauge suitable for withstanding the severe usage to which barrels of this character are frequently subjected. The barrel comprises a body or shell Ill formed preferably of two similar bowlshaped sections of rather deep dimensions arranged with their annular proximate edges in abutting relation to each other and welded together as indicated at l2. The heads it of the barrel have a shallow dome shape, and the junction between the Walls forming the heads and the side wall It of the barrel are of arcuate section as shown at the terminals ill. The usual bung hole fitting 20 is inserted in an aperture located centrally of the shell or side wall It, said fitting fill-being anchored to the margin of the aperture in any suitable manner, preferably by a leak-proof seam weld. Sheet metal bilge hoops 22 of U-section have lateral wings N which are Welded to the bilge region of the barrel to constitute rolling tracks or rings at the sides of the bung hole fitting 20.

The chimes 28 at the barrel terminals are made of separate blanks of sheet steel that are assembled with and anchored to the barrel in a novel and effective manner. The construction and arrangement of these chimes is such that they effectively reinforce and support the ends of the barrel, and they also provide suitable hand grips by which the barrel may be lifted. Each chime comprises an annulus of approximately L-shape cross section, having a radially inwardly extending flange 32 and an axially longitudinally extending flange 3t, the latter constituting the outer peripheral wall of the chime. Reinforcing means for strengthening the chimes extend transversely of the flanges 32 and 34 respectively and preferably take the form of a plurality of channels or indentations 32a and 34a concave surface of this embossment 38 conforms to the convex surface of the curved corner or arcuate terminal region l8 of the barrel. An abutment is made on barrel wall 16 proximate the curved corner region l8 by providing a well defined annular shoulder 40 in said wall.

In assembling a chime on the barrel the longitudinal supporting or axial flange 34 is telescoped on the end of the barrel shell so that the annular boss 38 will fit over the curved corner region 18 of the barrel and the marginal end edge of flange 34 will engage the abutment shoulder 40 on the barrel wall. After being positioned in this manner the chime is permanently anchored to the barrel by a suitable welding as at a: which unites thecontacting portions of the shell and chime. It willbe seen that when the chime has been assembled with thebarrel, the radially inward flange 32 projects above and overhangs the The tap fitting 42 is secured in a novelman ner at a tap hole in the central region of a head [4 to facilitate inserting the tap rod or: tube into the barrel. As shown in Fig; 1, this fitting 42 comprises an axial tubular stub 44 terminating at its inner end back of head I4 in an annular flange 46 having a shouldered portion 48 on its surface next said head. There is a depressed region 50 in the domed head l4 which is located centrally thereof. In the central portion of this depression there is a tap hole that is surrounded by an annular flange of L-section the upstanding portion 52 of which flange preferably contacts the edge of fitting flange 46. The radial portion 54 of this flange rests on the outer surface of said fitting flange in abutting relation to the shoulder 48.

For the purpose of assisting in anchoring the tap fitting in place, an annular bracket 56 is provided which is made of stamped sheet steel, and is so constructed and arranged as to provide a rigid reinforcement for the assembly. This annular bracket has an inverted dish-shape in cross section and is arranged in overlying relationship to a portion of the head l4 beyond the depression 50. The inner margin of bracket 56 is formed with an axial flange 58 terminating in a radial flange 60 which is superposed on the radial flange 54 of the barrel head.

The overlying portions of the head, the fitting flange and the bracket are united by an outside weld 64. Thus the superposed radial flanges 54 and 60 of the head and bracket are anchored to each other and are securely attached to the fltting flange at shoulder 48 by the outside weld which provides a visible leakproof seam.

It will be seen the highest portion of the bracket 56 is back of or beneath the plane of radial flange 32 of the chime 28, and the outer end edge of tap fitting stub 42 is back of or beneath the plane of the high portion of bracket 56. In this manner the bracket and the tap fitting on the barrel head are well protected by the chime 28 when the barrel is up-ended and resting on a chime.

all

Hence, damage to the tap fitting and bracket are avoided, and rupture of the welds 62 and 64 is prevented. Furthermore. any accidental leakage through a ruptured hidden seam is an impossibility with the present structure due to the fact that all the welding is on the exterior of the barrel head where any leakage will be visible and may be readily repaired without dismantling or removing any portion of the barrel.

While the present invention has been described in a typical or preferred embodiment thereof, it will be apparent to persons skilled in the art that changes or modifications thereof may be made without departing from the spirit of the present improvements. It is aimed in the appended claims to cover all such changes or modifications.
